1  Scope  p. 12

The scope of this Technical Report is to study further enhancements of the 5GS to support Non-Public Networks including the following aspects:
  1. Support for enhanced mobility by enabling support for idle and connected mode mobility between SNPNs without new network selection.
  2. Support for non-3GPP access for SNPN.
  3. Address SA WG1 requirements in TS 22.261 related to support for Providing Access to Localized Services.

3  Definitions of terms, symbols and abbreviations  p. 13

3.1  Terms  p. 13

For the purposes of the present document, the terms given in TR 21.905, TS 23.501 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
Local service, Localized service:
Service, which is localized (i.e. provided at specific/limited area) and/or can be bounded in time. The service can be realized via applications (e.g. live or on-demand audio/video stream, electric game, IMS, etc), or connectivity (e.g. UE to UE, UE to Data Network, etc.).
Localized service provider:
application provider or network operator who make their services localized and to be offered to end user via a hosting network.
Hosting network:
A network providing access to Local/Localized services.
Home network:
A network owning the current in use subscription/credential of the UE. Home network can be either PLMN or NPN.
Home network service:
Service, which is offered to UE based on subscription agreed with home network operator.
Return to home network:
UE leaves the hosting network (e.g. when the Local/Localized service is terminated), and resumes to use subscription/credential of home network. It can involve a network selection (e.g. select HPLMN or VPLMN) as specified in TS 23.122, and can involve deactivation/activation of SNPN access mode.

3.3  Abbreviations  p. 13

For the purposes of the present document, the abbreviations given in TR 21.905, TS 23.501 and the following apply. An abbreviation defined in the present document takes precedence over the definition of the same abbreviation, if any, in TR 21.905, TS 23.501.

4  Architectural Assumptions and Requirements  p. 14

  • Solutions shall build on the 5G System architectural principles as in TS 23.501, including flexibility and modularity for newly introduced functionalities.
  • Functionality to enable regulatory services like emergency services are assumed to re-use existing architecture mechanisms with no or limited impact.
  • Hosting network can be NPN, i.e. SNPN, or PNI-NPN.
  • Home network can be NPN or PLMN.
  • The term "home network" does not imply a roaming relationship.
  • Only subscribers of a public network can roam into a PLMN.
